The DimensionEngine calculator converts units and solves equations using any units  metric, English, or mixed. The engine does all needed conversions automatically, so you don't have to. There are no pulldown menus, and you aren't limited to a preprogrammed set of units. It's fast, easy, and free. Plus it's all text, so you can easily copy, paste and share your work.
Suppose you want to convert 10 inches into centimeters. In the window under the INPUT tab,
The results automatically appear in window under the OUTPUT tab.
Your work is saved under the
INPUT
tab, so you can quickly and easily go back, edit any mistakes, and resubmit.
Use the CLEAR button to clear you INPUT.
INPUT:
10 inches; cm
To convert the same INPUT into multiple outputs:
To convert different INPUTs all at once:
INPUT:
10 inches; cm; ft
5 miles/hr; m/s; kph
Use dimensional values in equations and let DimensionEngine do all the conversions for you.
INPUT:
3 cm * 5 in + 10 ft^2
Use dimensional variables to simplify your equations and INPUT.
INPUT:
x = 3 cm
y = 5 in
z = 10 ft^2
area = x * y + z; ft^2
frac_z = z / area
DimensionEngine has an extensive library of math functions, engineering constants, and userdefined functions.
INPUT:
# Density of a Baseball
d = 9.39 in
vol = (4/3) * pi() * (d/2)^3
w = 21 oz
rho = w / (grav() * vol)
